HD Coupling 5mm to 1/4

The Radio Active HD Coupling 5mm to 1/4 (I-RMA5752) offers a robust solution for joining a 5 mm shaft to a 1/4 inch shaft in RC and model engineering projects. Ideal when mixing metric and imperial components, it provides a secure and accurate link between differing shaft sizes.

Applications and Sizing

This heavy-duty coupling bridges 5 mm (metric) and 1/4 inch (approximately 6.35 mm, imperial) shafts, making it useful across a wide range of drive systems where those sizes are used. It is well suited to general drivetrain tasks where a reliable, concentric connection is required.

Suggested Compatibility

• Drive trains using 5 mm motor output shafts
• Assemblies requiring connection to 1/4 inch shafts (approx. 6.35 mm)
• RC models and bench projects where mixed metric/imperial shafts are present
